FIELD OF THE INVENTION

This invention relates to jigs and fixtures for aligning, guiding, and/or holding a workpiece on woodworking machinery during a woodworking operation.

BACKGROUND OF THE INVENTION

Woodworking often employs a multitude of tools and machines to accomplish a variety of intricate operations. Challenges abound in addressing the ever-present desire to enhance efficient woodworking tools, machines, and methods. For instance, attempts have been made to improve the use of pocket hole jigs by enhancing access to the drill guide, such as by providing activation of the clamp from the same side as the drill guide. However, in that attempt, the construction and operation of the clamp mechanism required increased clearance and caused interference with the support surface upon which the pocket hole jig was placed or mounted. In a further attempt to address these interference issues, the base thickness was increased to provide additional clearance for the clamping mechanism, which ultimately resulted in a less efficient design that was bulk and more costly. The devices, systems, and methods disclosed herein provide inspired perspectives that address various woodworking issues faced by modern-day woodworkers.

SUMMARY

Jigs and fixtures for aligning, guiding, and/or holding a workpiece on woodworking machinery during a woodworking operation are described, as well as methods of making, modifying, and using jigs and fixtures. For example, a modular track and flip stop with a corrugated surface on the top and face of the track as well as a mating corrugated pattern on the bottom and top of the flip stop base are described. In addition, a flip stop base created from two identical mating parts that allows the top and bottom to be separated so the bolt can be moved without the need to disassemble the bolt and flip arm assembly is disclosed. Moreover, a modular miter gauge head and bar system for easily making custom, jigs, fixtures and sleds are disclosed. Other systems, methods, and variations on the preceding are also disclosed.

The foregoing and other objects and advantages of the invention will appear in the detailed description which follows. In the description, reference is made to the accompanying drawings which illustrate preferred embodiments of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the invention are illustrated in extensive detail in the accompanying FIGS. 1-65, as set forth above in the description of FIGS. 1-65, and as elaborated below in the detailed description. As shown in FIGS. 1-65, jigs and fixtures for aligning, guiding, and/or holding a workpiece on woodworking machinery during a woodworking operation are described, as well as methods of making, modifying, and using jigs and fixtures. For instance, a modular track and flip stop with a corrugated surface on the top and face of the track as well as a mating corrugated pattern on the bottom and top of the flip stop base are also described. Moreover, a flip stop base that may be created from two identical mating parts that allows the top and bottom to be separated so the bolt can be moved without the need to disassemble the bolt and flip arm assembly is further disclosed. In addition, a modular miter gauge head and bar system for easily making custom jigs, fixtures, and sleds are disclosed.

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific preferred embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that mechanical, procedural, and other changes may be made without departing from the spirit and scope of the present inventions. In addition, while the various embodiments identify example or preferred hardware (e.g., bolts, thumb screws, etc.) capable of incorporation, given the benefit of this disclosure one skilled in the art will appreciate that a variety of alternatives are available to accomplish the relevant constructions, including both use of off-the-shelf hardware and/or custom specification components.

FIGS. 1 through 8 disclose a holding device, such as for use with the KREG pocket hole drill guide 12 of the KREG K4 pocket hole jig 10. While reference is made throughout to various available devices, for example the KREG K4, given the benefit of this disclosure one skilled in the art will appreciate that the concepts described herein can be adapted in a variety of manners that are within the scope of the inventive concepts. The L-shaped adapter plate 39 holds the pocket hole drill guide 12 at a 180 degree rotation from the usual orientation so that the operator can clamp the workpiece 14 and drill a pocket hole from the same side of the jig. This design avoids the problem of the operator having to reach around a large panel workpiece to be able to operate the clamp, while providing an efficient, interference free jig construction. Notably, the discontinued KREG K3 and the KREG K5 17 pocket hole jigs allowed same-side drilling and clamping but suffered from the above-noted deficiencies, and no device offers the same advantage for the most popular KREG K4 pocket hole jig 10.

FIG. 1A is a perspective view of a modified KREG K4 pocket hole jig 10 and an L-shaped adapter plate 39 which secures the drill guide to the pad of the toggle clamp 20. The illustration is shown with a panel workpiece 14 positioned for drilling the pocket hole. The drill guide 12 has been removed from the usual holding cavity 95 and has been rotated 180 degrees and is secured to the L-shaped adapter plate 39.

The clamp 18 presses the drill guide 12, which is secured in the L-shaped adapter plate 39 against the workpiece 14 for the purpose of drilling an angled pocket hole. This allows the operator of the KREG K4 10 jig to both clamp and drill the workpiece 14 from the same side rather than having to reach around a panel to engage the clamp 18. FIGS. 1 through 8 illustrate the process of using the rotated drill guide 12 and the L-shaped adapter plate 39. The KREG K4 10 is illustrated with a track 97 and flip stop system 16. The mating surfaces of the T-slot track 97 and the flip stop assembly base 16 have a matching corrugated 64 design for a secured fit. FIG. 1B is an enlarged view of the adapter plate 39 shown with the semicircular cavity or opening 35 which houses the pad of the example clamp 18. The clamp 18 can be a variety of clamping members that provide some form of axial force to urge the adapter plate 39 toward the workpiece, such as a hydraulic ram, screw jack, and the like. FIG. 1C is an enlarged view of the adapter plate 39 shown alone. It illustrates the semicircular cavity 35 which encircles the clamp pad 20. The adapter plate 39 is configured to establish a selective axial coupling with a clamping member, such as the clamp 18. The cavity 35 of the adapter plate 39 allows the adapter plate 39 to be moved transversely to the clamping axis to achieve coupling and uncoupling of the clamp 18 and the adapter plate 39.

FIG. 2A is an exploded view of the KREG K4 pocket hole jig 10 illustrated without the drill guide 12. The dotted line illustrates that the middle of the clamp pad 20 lines up with the middle of the semicircular opening 35 which houses the pad 20 of the clamp 18. The opening of the drill guide cavity 94 is filled by a spacer 45 extrusion made, for example, from plastic or aluminum. Alternatively, for example, the spacer 45 can also be made from two matching halves thus the extrusion would be half the size of the one illustrated. When the spacer 45 is seated into the drill guide cavity 94 a generally continuous surface is established against which a workpiece 14 can rest, which also provides a convenient and economical approach to adapting the KREG K4 pocket hole jig to accommodate features of the inventive concepts.

FIG. 3A is a top perspective view of a modified KREG 4K pocket hole jig 10 with a track 97 and flip stop assembly 16 illustrating the shape of the modified U-shaped extruded spacer 45 fitted into the drill guide cavity 94. FIG. 3C is a top perspective view of the modified U-shaped extrusion 45 featuring a small indentation in the two corners 81 that inter-fit with the form factor of the example pocket hole jig 10. The extrusion 45 can be adapted to accommodate any relevant form factor established by the mating assembly.

FIGS. 9 through 17 describe a T-slot based track and stop system featuring a corrugated surface 64 on the mating surface of the track extrusion 61 and the bottom of the stop base 66 and the two part base 67. The usual practice is to have a bottom of a stop base fit into a T-slot opening of a track. However, the fit is often not accurate causing the flip stop to wiggle on the track, thus decreasing measuring accuracy. As an aluminum extrusion die wears, the sharpness of the extrusion decreases, increasing the likelihood of a loose fit. The locking corrugated surfaces 64 of the corrugated extrusion track 61 and the corrugated stop bases 66 and 67 lock securely with minimal clamping pressure.

The table miter slot 108 secures the bar 110 of the miter gauge and prevents it from rotating. The miter gauge is a useful tool that the average woodworker already has. The workpiece 14 can be supported by the table saw table top 106 such that the workpiece 14 can rest directly on the table top 106. A wide board or panel is preferably supported on each side of the standard pocket hole drilling device such as the KREG K4 pocket hole jig 10. The height of the KREG K4 pocket hole jig 10 floor is 1 inch from the work bench or saw table top 106. Supporting a large panel workpiece with a 1 inch thick support piece requires use of a non-standard wood thickness.
